Doctors are not known to be engineers, but innovation knows no boundaries, only inquisitiveness!
Dr. Prithvi Chandrakanth, a postgraduate resident of the Department of Ophthalmology at Sri Manakula Vinayagar Medical College and Hospital has designed a device — the T3 retcam (Trash to Treasure retina camera) — by recycling hand sanitizer bottles, to take photos and videos of the retina of the eye.
Fundus cameras, used for taking photographs of the retina, are very expensive and heavy. Most of the fundus cameras also do not have a video recording facility. The T3 retcam was made with a used hand sanitizer bottle, modified to house a 20D lens (condensing lens used by Ophthalmologists to do indirect Ophthalmoscopy to view the retina) at one end and a smartphone at the other end of the bottle.
